Dissolve the Preferment in the water and add all flour. Mix well and let it rest for 30 minutes (autolyse) or mix it with your food processor on lowest speed. Kneed it for 10 minutes on lowest speed and add the salt. Continue for 3-4 minutes.

Let it now rest for 2,5 hours at room temperature (about 24 degree) and make a fold at 30, 60 and 90 minutes (in the bowl). At the end, make on Stretch & Fold and put it back into the bowl for the final rise. Let it now finally rise for 1,5 hours at warm temperatures (about 30 degree).

Remove it very carefully from the bowl onto a floured surface and divide it into two long pieces. "Form" it as baguette - which means more or less not to degas it anymore, just move it in shape. For Rolls, just move the dough on a floured workplace and shape it as rectangle. Cut into pieces and bake it. Bake it at 270 degree dropping to 240 degree with steam. Remove the steam after 15 minutes and continue with baking for 15 minutes (at all 30 minutes or until it is medium brown or darker, depending on your taste).
